// Package cache implements event-driven cache layer
|
|
// that is used by auth servers, proxies and nodes.
|
|
//
|
|
// The cache fetches resources and then subscribes
|
|
// to the events watcher to receive updates.
|
|
//
|
|
// This approach allows cache to be up to date without
|
|
// time based expiration and avoid re-fetching all
|
|
// resources reducing bandwidth.
|
|
//
|
|
// There are two types of cache backends used:
|
|
//
|
|
// * SQLite-based in-memory used for auth nodes
|
|
// * SQLite-based on disk persistent cache for nodes and proxies
|
|
// providing resilliency in the face of auth servers failures.
